Bug 24876: Fix capitalization on patron search for holds

When placing a hold in the staff interface, the heading on the
search box reads: Search Patrons or clubs
The patch changes it to be Search patrons...  instead.
Also changes club id to club ID.

To test:
- Place a hold in the staff interface
- Verify the capitalization error
- Switch tabs to Clubs, see: club id
- Apply patch
- Verify it's all good now
